wicked whims How to edit Default skin to be compatible with WIcked Whims?

[MythicSimmer]

Hi! I've been using WW for awhile now, but none of my CC skins (default replacements) are compatible. I know my way around S4S a little bit, and I'm looking for some kind of tutorial to update my skins to work with WW. The only thing I found was from 2018 but it doesn't work anymore and I'm hoping someone around here knows the way to get this sorted. Thanks!
